PH strip tester

A PH strip tester is a simple and effective tool used to measure the acidity or alkalinity of a solution. It typically consists of a strip of paper or a small piece of material impregnated with pH indicators. These indicators change color based on the pH level of the substance being tested

The strip contains pH-sensitive indicators that react with the hydrogen ions in the solution. This reaction causes the strip to undergo a color change. The resulting color corresponds to a specific pH level.
